BOTTEGA, Daline B.; BOICA JUNIOR, Arlindo L.; SOUZA, Bruno H. S.  and  LOURENCAO, André L.. Biological aspects of Tuta absoluta (Lepidoptera: Gelechiidae) reared on leaves of different tomato genotypes. Rev. de Ciências Agrárias [online]. 2015, vol.38, n.2, pp.139-148. ISSN 0871-018X.

The resistance of tomato genotypes, Lycopersicon esculentum (Miller) (cv. Santa Clara, hybrids: Saladette Italian Ty Tyna, Santa Cruz Débora Ty, Salad Lumi and Saladette Italian Andrea Victory), Lycopersicon hirsutum f. glabratum (C,H, Mull.) (lines PI 134417 and PI 134418) and Lycopersicum pimpinellifolium (Just) (lines NAV 1062 and PI 126931) to Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) was evaluated under laboratory conditions. The line PI 134418 had the most negative effect on T. absoluta in comparison to the control (Santa Clara), lengthening the larval stage and reducing larval and global survival. The line PI 134417 also affected the development of T. absoluta lengthening the larval stage and reducing the larval survival. The other genotypes showed no negative effect on the biology of T. absoluta. We concluded that PI 126931 is susceptible and NAV 1062, Santa Clara, Tyna, Débora, Lumi and Andrea Victory are highly susceptible to T. absoluta, whereas PI 134418 and PI 134417 highlighted with high resistance and moderate resistance, respectively, to T. absoluta of antibiosis-type.
